To all whom it may concern:

Be it known that I, FLOYD MoNRoUGH CRANK, a citizen of the United States of America, residing at Muskogee, in the county of Muskogee and State of Oklahoma, have invented certain new and useful Improvements in Headlights for Automobiles, Locomotives, &c., of which the following is a specification.

My invention relates to improvements in head lights for automobiles, locomotives, etc.

The object of the invention is to provide specific means for mounting the lamps so that in the rotation of the stems thereof friction is reduced to a minimum.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawing;

Figure 1 is a perspective view illustrating the application of my invention.

Fig. 2 is a detail perspective view of the lamp actuating mechanism.

Fig. 3 is a plan View of the same.

Fig. l is an enlarged detail section of one of the lamp supports.

The invention is shown as applied to an automobile but it is to be understood it is applicable to any other type of vehicle where it is necessary to turn the lamp as the vehicle rounds a curve.

To the frame of the automobile are attached brackets 11 connected by a cross rod 2. Each bracket is formed with a vertical collar 3, to provide supports for the lamps. As the lamps and their mountings are exactly of the same construction, but one will be described.

4 indicates a vertical sleeve clamped in the collar 3, and provided on its upper end with an enlargement 5, the flange of which rests on the top edge of the collar, while the lower reduced end of the sleeve is threaded at 6. Extending through the vertical sleeve 4, is a tube 7, on the upper end of which is a beveled head 8, which receives the lamp 9. Below the head 8, is a flange 10, which is beveled on its upper edge, and which fits in the enlarged portion 5 of the sleeve. Between the bottom of the flange 10, and the top of the enlarged portion 5, are balls 11, to form an anti-friction bearing for the rod. A hollow nut 12, is mounted on the rod 7 below the head 8, and the threaded portion engages the interior threads on the enlarged portion, balls being interposed between the flange 10,

and the bottom of the nut to provide an antifriction hearing.

The lamp is provided with a threaded stem, and a clan'iping nut 18, on the rod 7, clamps the lamp to the head 8.

The rod 7, projects below the sleeve 4:, and a hollow nut 16, engages the threads 6, balls being interposed between the bottom of the sleeve and the interior of the hollow nut to provide an anti-friction bearing.

The nut 12, is fixed to the enlarged portion of the sleeve by a set screw 17, and the nut 16, is fixed to lower end of the sleeve by a nut 18. The rod 7 is fitted loosely in the sleeve to readily permit of rotation of said rod on the ball bearings.

To the lower ends of the rods 7, are bolted crank arms 18, 18 the arm 18*, being longer than the arm 18, and provided with a series of openings 20. The two crank arms are pivotally connected by a rod 21, and to the crank arm 18, is pivotally connected a rod 22, pivoted to a clamp bolted to the steering mechanism.

In operation as the steering wheels are turned to round a curve, corresponding motion is imparted to the rods carrying the lamps.

The invention herein described is particularly directed to the sleeve and the means associated therewith to provide a simple and inexpensive means to permit ready turning movement of the lamps by the steering mechanism.

hat I claim is.

1. In an apparatus of the class described the combination of a bracket provided with a collar, a sleeve clamped in the collar and provided with an enlarged internally threaded head, a rod loosely fitting in the sleeve and provided with a flange which operates in the enlarged head, balls interposed between the flange and the head, a threaded nut on the rod and fitted in the top of the head, balls interposed between the top of the flange and the bottom of the nut, means for fixing a lamp to the top of the rod, a threaded nut on the bottom of the sleeve, and means extending from the rod to cause same to turn with the wheels of a vehicle when rounding a curve.

2. In an apparatus of the class described, the combination of a bracket, a sleeve clamped in the bracket and provided with an enlarged internally threaded head, a rod loosely fitting in the sleeve and provided With a flange which operates in the enlarged head, balls interposed between the flange and the head, a threaded nut on the rod and fitted in the top of the head, balls interposed between the top of the flange and the bottom of the nut, means for fixing the lamp to the top of the rod, a threaded nut on the bottom 10 of the sleeve, balls interposed between the bottom of the sleeve and the nut on the bottom of the latter, and means from the rod to cause same to turn with the wheels of the vehicle when rounding a curve.

In testlmony whereof I afiix my signature 1 Copies 0! this patent may be obtained for five cents each, by addressing the Commissioner of Patent; Washington, D. C.
